Metals refining

Ferrous metals and ferroalloys processing

Outotec offers leading technology solutions and services for the processing of iron ores and other ferroalloys materials in the entire value chain from ore to metal. We provide energy-efficient and cost-effective methods based on extensive research and development together with lifecycle services which ensure sustainable operations.

Our agglomeration process alternatives include both traditional travelling grate pelletising, emission optimized sintering and steel belt sintering. For smelting our portfolio includes the innovative shaft kiln preheating, submerged arc furnace (SAF) smelting and direct current (DC) smelting.

Our one hundred year long experience in the mining and metals sector and operation of metallurgical plants enables us to offer the widest range of sustainable technological solutions and services for new green field or brown field plants as well as modification of existing facilities.

We have comprehensive research and development capabilities with pilot plants for testing the customers' raw materials. Throughout our history, we have been successfully developing innovative technologies for metallurgical plants at our research centers in Finland and Germany as well as in co-operation with customers’ plants.
